Aprim'ary object of thisinvention is to provide a method and means forpermanently waving hair which will eliminate the so called settingoperation, after the waving operation, which is,

my in virtually all permanent waving sys-, 1n heretoforeknoWn;

whether the wave is imparted by means of electric resistance heat, heatfrom an exothermic chemical reaction, or by so-called cold wavingimparted by a chemical treatment of the hair without the use of heat,after the wave is imparted, each waved tress must be removed from thecurler around which it is wrapped, and then re-set or styled into theform in which it is to be worn. This involves setting the tresses intodifierent formations than those in which the wave was given.

By use of the present invention this series of steps is eliminated sothat when the curls are formed and processed the desired curls andstyling are formed and determined in one operation. Thereby the settingoperation ordinarily necessary is eliminated.

Generally-in using the devices of this'invention in permanent waving-atress of hair is wound-u ona=-spindl which is preferably innit-ediournaiedrelation to a base or di'se' member which is re= silint 7 and'slotted. After "being wound in coiled form on' the spindle almost td'thescalp, the -p'rox imal portion of the-* tressis p'as'sed th'roughtheslotted" p'brtion' of" the di's'c -and' thespindle bear ingthe coilof hair is their rotated with" respect? to the disc" tensioning" thetress andforci-n'g the dis'cjagainst-the scalpr- 7 Referring n'ow' ii'i'd'etail to the accompanying? idrawings, Figure 1 shows' a spindle ihaving a long-itiidinai'slot-fi Said spindle is journaled 'ima dischavingja slott termin'ati'ng in an enlargediinnenporti'unt.

Preferably the spindle l'is-iformed ofarelatively' Q- rigid materialsuch as a thermosetting' resin,

while the -di'sd 3"is "made of aflexible resilient material suchas-rubb'er. The spindle, in the"em-- bodimen't of Figures. 1 and 2 hasnear one end thereof a pair of flanges} 'I a'nd Bi The distance betweensaid flanges is=less than the normal is attached to said spindle I, theportion of the disc positioned between said flanges and 8 will becompressibly retained. Such a structural rela tionship will maintain thespindle and disc in normally fixed relation, yet will permit relativemovement under cooperative frictional restraint.

Flange 1 is preferably beveled oil so that when the disc 3 is in contactwith it and flange 8 the periphery of the flange 'I and the adjacentsurface of disc 3 will provide an uninterrupted surface so that when atress of hair is wound on the device it will be diflicult for any randomstrands of hair to be caught between the flange and the disc therebytending to result in a more perfect wave and eliminate a possible sourceof discomfort to the recipient of the wave. To further this purpose,flange 8 is preferably of a smaller diameter than flange 1. Additionallysuch disparity between the diameters of said flanges will facilitateassembly of the spindledisc structure.

Figure 3 shows the distal end II of a tress of hair I0 placed in theslot 2 of spindle l in the initial step of the winding operation.

The tress is then wound on the spindle toward the proximal end of thetress until the device is quite near the scalp. The proximal portion ofsaid tress I0 is then passed through the slot 4 to its enlarged innerportion 5. The disc is then held against movement and close to the scalpwhile the spindle I is further rotated with respect to the disc so thatthe remainder of the tress I0 is wound and tensioned. on said spindle,forcing said disc 3 against the scalp, as shown in Figure 4, where it isretained until the waving action is completed.

Figihe 5 is an alternative embodiment of the invention showing a,spindle l5 adapted to rotate about a flanged bolt It which is attachedto a disc member [1, by a nut I8.

Said bolt IS when tightened with respect to said nut compresses saidspindle [5 in frictional bearing relationship against said base memberI1. the base member I1 has a slot 2| terminating in an inner enlargedportion 22, which are equivalent to the respective portions flange 1 andslot 4 and inner portion 5 of Figures 1 and 2.

The devices and methods of this invention are particularly adapted foruse in the cold permanent waving methods which customarily are given inthe form of Croquignole waves with the customary waving and neutralizinglotions known in the art. In such cold waving this invention has anadditional advantage that after the waving lotion has acted on the tressunder tension the spindle can be somewhat loosened to relax the hairduring the neutralizing step to facilitate complete penetration of thetress, particularly that portion closest to the spindle. The tress canagain be re-tensioned if desired." The waving solution may be applied tothe tress before winding, as in so-called wet winding, or after thewinding is completed.

Such control of the tension of the curl on the spindle permits accuratecontrol of the tightness of the curl ultimately imparted. Therefore, ahead of hair may be waved in a predetermined pattern, withthe'elimination of the usual guesswork about the outcome. Consequentlyas one style is sketched or otherwise indicated by a hair stylist, thewave may be competently given by a relatively inexpert operator.

When the devices of the invention are used in exothermic machinelesswaving it is necessary,

Said spindle has a flange member 20, and

4 of course to provide a protective insulating sheet, as of felt or thelike, between the curler and the scalp to protect the scalp from steamor condensate from the chemical reaction of the machineless waving pads.

Naturally, in this type of waving, the spindle would not be made ofplastic material but prefer ably a metal such as a light aluminumalloy.-

Other means than those illustrated and described of providing theoperating relationship between the spindle and the base member ofnormally fixed but relatively rotatable connection will be apparent tothose skilled in the art.

The invention in its broader aspects is not limited to the specificmechanisms shown and described but departures may be made therefromwithin the scope of the accompanying claim without departing from theprinciples of the invention and without sacrificing its chief advantage.

What is claimed is:

A device for winding a tress of hair preparatory to permanently wavingthe same, said device comprising a flexible resilient disc having athrough opening and a slot which extends inwardly from the periphery ofthe disc, and an elongated slender rigid spindle consisting solely of arod-like member having its lower end frictionally received in theopening in the disc and having a pair of flanges frictionally engagingopposite faces of said disc whereby said disc and spindle normally willrotate together and said spindle can be rotated relatively to said discunder frictional restraint, said spindle having a slot for engaging andretaining an end of a tress.
